I have run Arch for two years on a tiny personal server. It is fun but depending on how you use it and what Alan is currently breaking, it can be a lot of fiddling.

Just as one example, sysvinit - systemd migration took some careful file editing not to botch things remotely. At one point, merging all binaries in /usr/bin incentivized me to move from the no longer supported GRUB-legacy to GRUB2. GRUB2 installer failed leaving a zombie process that prevented anything from touching the mbr...

I wiped it, installed Wheezy and I can tell you that it requires far less maintenance and you can still pull bits and pieces from testing if you really want to.

Go for Arch! Enjoy pacman and be on the bleeding edge. Added bonus: new performance improvements will hit your tiny server faster, thus: more speed :)!

Arch is definitely a viable option for a personal server.
